SASH-PULLEY.

SPECIFICATION forming part of Letters Patent No. 350,195, dated October 5, 1886.

Application filed March 527', 1894.

To aZ Z whom it may concern Be it known that ],\VILLIAM GOFORTH, a citizen of the United States, residing at Windsor, in the county of Henry and State of Missouri, have invented certain new and useful Improvements in Sash-Pulleys; and I do declare the following to be a full, clear, and ex act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which. l'orm a part of this specificaiion.

Hy invention relates to pulley-stops intended especial] y for use in sashes; and it consists in the novel construction, combination, and an rangelnent of the several parts, as will be hereinat'ter described and claimed.

In the drawings,.Figure 1 is a perspective view of p a pulley and bearing-bracket constructed according to my invention. Figs. 2 and 3 are front views. Fig. 4 is an edge view of same. Fig. 5 is a side view of the pulley. Fig. 6 shows a modification, all of which will be described.

The pulley A is of ordinary construction, having an annular groove forming the edge flanges, a a. One of these flanges is cut away slightly at I), and has at one end a point or prong, Z), which, it will be seen, projects upward when the pulley is applied in the operation of the device. The bearing-bracket is composed of the face-plate 0 and the boxing D, provided with a journal, (7, for the pulley. The faceplate has a slot, E, through which the periphery of the pulley projects, as clearly shown. Ihis slot has a notch or lateral wing, 6, cut out near its upper end on the side next the notch in the pulley-flange, and the slot above said wing or notch is contracted, forming a point, e, which projects over the pulley and in about a line with the point in the flange thereof, as most clearly shown in Figs. 2 and 3.

In operation, when it is desired to clamp the rope fagainst the action of the sash-weight F, the rope should be drawn laterally into the notch in the face-plate, so it will be engaged by the point of the pulley-flange, or between same and the point of the face-plate, when it will be securely held, and the sash may be Serial No. 125,735.

easily handled in order to wash it, or for other desired purpose. I

It is manifest that my pulley could be used for the purpose of clamping the rope without the notch or point of the face-plate. To illustrate this, suppose the pulley be removed and turned so as to bring the notched flange therein next the opposite side from that having the notch, and invert the faceplate so as to bring its present lower end the upper one. It will be seen that in this case the rope could be drawn in the slot in the pulley and would be clamped therein against the wall of the slot in which the pulley works. I prefer, however, to use the wing or notch in the slot of the faceplate, as thereby a more certain and firmer clamping 01' the rope is secured.

\Vhile I have only described the use of the invention in connection with a face-plate, it is obvious such face-plate could be dispensed with and the slot formed in the sash-frame, the pulley being journaled in any suitable supports and arranged to turn through said slot, as desired.

It will be appreciated that the notch in the pulley could be made without the binding point or prong at one end, and would clamp the rope, especially when used in connection with the pulley-slot having a notch or wing extended therefrom; but I prefer to form it with said points for the purpose of greater security and better action.

In Fig. 6 I have shown the pulley as provided with a notch in one of its flanges, said notch being provided with binding points or prongs at both ends, so that when one prong becomes dulled by use the pulley can be reversed to bring the other one into position for the operation. Obviously the pulley might be provided with more than one notch where so desired, in order that the rope might be clamped readily at any desired point.

Heretofore pulleys have been widened on one side of the circumferential groove, and said widened portion has been provided with oblique grooves for the reception of the rope, which is clamped therein between the widened and oblique-grooved flange and a lug projecting from the pu1ley-block and extending in close proximity to said flange. I am also aware that pulleys have been cut on one side to form a series of notches which start near the center and widen toward the edge to re ceive the rope, which is joined between one of the uncut portions and adjacent side of the pulley-hanger. My invention differs materially from such devices in the manner speeifically recited in the claim Having thus described myinventioinwhat I claim, and desire to secure by Letters Patent,

The herein shown and described sash-pulley, comprising the following elements in combination: face-plate 0, provided with the 1ongitudinal slot E, having the notch e to, one side thereof, forming the overhanging point e, and the flanged pulley A, journaled to the faceplate and projecting part way through the slot', and having a notch, I), out in the flange adjacent the notched side of the slot E, forming a projection, .b, to coact with the overhanging point e, as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
